Drag Knife - Beta!

**This is only a design - it has never been tested!** I do not know if it will work.

It is a drag knife for a CNC machine.

*You will require:*
Strong 8 or 9mm diameter magnet (this is what holds it to a shaft in the cnc)
Blades (dimensions pictured) I tried to make it flexible for other sizes.
M4 30mm (or 25mm) bolts, quantity 3
M4 nuts, quantity 3
2 skateboard bearings
8mm cylindrical ferris metal shaft to fit into your CNC - I'm *planning to just use the other end of an 8mm drill bit.


- it's not finished yet (it may never be :) ), but some folks have indicated interest and I am keen to offer this design for experimentation.
